Extreme vetting

Extreme vetting is a policy which was first proposed by US Republican Party presidential nominee Donald Trump on 25 July 2016. "Extreme vetting" would involve ideological screening of immigrants coming to the United States, in which those who did not "share (American) values and respect (American) people" would be deported. This policy was a part of Trump's proposed ban on Muslim immigration to America, and it was similar to Trump's plan to only allow Christian Syrian refugees to enter the USA.
